This applied voltage changes the alignment state of liquid crystal molecules to produce a display.
本発明の効果は大別して、次の３種を挙げることができ
る。The effects of the present invention can be broadly classified into the following three types.
１ 本発明で用いているスペーサ部材は、基板の周辺部

９基板間の間隙を保持する事が出来る。1. The spacer member used in the present invention can maintain the gap between the nine substrates over a larger area compared to the conventional method in which a seal member is provided only at the periphery of the substrate.
２、本発明で用いているスペーサ部材は、表示面の非透
光性部分にスペーサ部材を設けているので、画像表示面
で液晶分子の配列を乱さない様にする事が出来る。2. Since the spacer member used in the present invention is provided in the non-light-transmitting portion of the display surface, it is possible to prevent the arrangement of liquid crystal molecules from being disturbed on the image display surface.
五 本発明では、スペーサ部材を表示面内に点在して設
けているので、半導体駆動素子が設けられた表示基板及
び対向電極基板のいずれか一方、または両方が可撓性フ
ィルムの場合にも、上記第１項及び第２項で述べた効果
を果たす事が出来る。5. In the present invention, since the spacer members are provided scattered within the display surface, the spacer members can be provided even if one or both of the display substrate on which the semiconductor drive element is provided and the counter electrode substrate are flexible films. , it is possible to achieve the effects described in the first and second terms above.
従来の方法では、上記第１項に対し、
１、 周辺部のみに設けたシール部（第２図１０）が基

つ必要があるのでシール部材の材料選択に制約を受は易
い。In the conventional method, in response to item 1 above, 1. The seal part (Fig. 2, 10) provided only at the periphery functions as a spacer member to maintain a constant gap between the substrates, and at the same time, it is used to fill the liquid crystal. Since it is necessary to have the function of a sealing member, there are easy restrictions on the selection of materials for the sealing member.
２、基板を薄くすると基板の変形が起とシ易く、例えば
４〜１０μｍの微小な基板間の間隙を保持する事がほと
んど不可能である。2. When the substrate is made thinner, the substrate is easily deformed, and it is almost impossible to maintain a minute gap between the substrates of, for example, 4 to 10 μm.
６ シール部材の変形が起とシ易いので、基板間の間隙
が１つのセルの基板面内で部分的に不均一になって表示
特性のムラを生じ易く、各表示セルに於いて基板間の間
隙がばらつき易い
等の欠点が生じていたが、本発明によれば、上記いずれ
の欠点も、同時に解決出来る。6. Since the sealing member is easily deformed, the gap between the substrates becomes partially uneven within the substrate surface of one cell, which tends to cause uneven display characteristics. However, according to the present invention, all of the above-mentioned drawbacks can be solved at the same time.
従来の方法では、上記第２項に対し、表示面に設けたス
ペーサ部材によシ、該スペーサを設けた部分の液晶分子
の配列に多少の乱れが生じ、表示面の画像が多少見苦し
くなる事があった。In the conventional method, regarding item 2 above, due to the spacer member provided on the display surface, some disturbance occurs in the arrangement of liquid crystal molecules in the area where the spacer is provided, and the image on the display surface becomes somewhat unsightly. was there.
本発明では上記の欠点を解消する事が出来る。The present invention can eliminate the above drawbacks.
上記第６項、即ち、半導体駆動素子が設けられた表示基
板及び対電基板のいずれか一方、または両方が可読性フ

部分で閾いられているので、シャープな見えを得ること
ができる。The drawbacks of the conventional methods can also be overcome in the case of item 6 above, that is, when one or both of the display substrate on which the semiconductor drive element is provided and the counter substrate are readable films. Furthermore, the present invention has the advantage that a display with excellent gradation and responsiveness can be obtained. Moreover, in the display panel of the present invention, especially in the case of color display in which a color filter is formed on the drain electrode, a sharp view can be obtained because each pixel is separated by a non-light-transmitting portion.
